3. Make a Position Check, as shown above. It is recommended to make the check at
28 kV. After the check the MPD automatically changes back to the previously
selected kV range.
4. Set kVp and mAs (or mA/time) to the desired values.
5. Make an exposure. The RTI logo flashes to indicate that the MPD has detected the
exposure.
6. Read the values in the RTD.
7. Repeat measurement for other generator set values.
There are some mammographic units that are bit peculiar when it comes
to kV measurements, for instance The Hologic Selenia and IMS Giotto. In
those cases, RTI have updated Application Notes, and there may be
some even for other units. Please check the RTI Electronics website (
www.rti.se) for the latest info. For Sectra MDM, Fischer Senoscan and
other scanning beam units, please see the section Scanning Beam
Mammography .
